RGC axon bundle width measurement procedure. A, A fibergram showing 400-μm radius analysis ring. Red dots indicate individual fibers from which thickness was measured. B, Magnified view of RGC axon bundle in panel A (green box). The red box shows the area to measure individual axon bundle width. The red lines highlight the locations to extract axon bundle intensity profiles. C, Average intensity profile of RGC axon bundle shown in panel B. The width of the axon bundle is measured at 1/e2 decay, as indicated by the red arrow. This is related to Figure 2. Download Figure 2-1, file.
